Help me please, very new to this

When i double click on a movie, it opens windows media player and in the bottom left of the screen it says "sending request for codec" and then says "error downloading codec".
It shows this on some and then opens others. What could i try for the ones that wont work, Please remember that i am a novice.
Thanks

I have downloaded xvid.

you're lacking a codec

click my upper anigif, download tsunamis filterpack 396 full, install it via custom routine and keep the default settings.

this should install all necessary codecs
